Indonesia faces big marine engineering challenges. The broad experience of Dutch engineers in protecting low-lying areas and the construction of land makes good cooperation possible.
Tanjung Priok is Indonesia’s main port and is situated in Jakarta Bay. It handles the majority of Indonesia’s exports and imports and is a lifeline for the majority of the country’s many thousands of islands. The port has become severely congested due to the increase in container traffic and lack of major port development over decades and therefore it is now undergoing one of the largest port extensions in the world.
Royal HaskoningDHV was commissioned by Indonesian Port Corporation (IPC) to supervise the construction of the port, including land reclamation, retaining walls, an access bridge, the container yard and quay structures. Van Oord was awarded a contract by PT PP (Persero) TBK for deepening the port and expanding and deepening the access channel. A total of 25 million cubic metres of material will be moved. Most of the material will be pumped into closed basins adjacent to the new terminal for further expansion of the port. Approximately 10 million cubic metres of sand will be removed from the seabed in preparation for construction of the new terminal.
Once completed in 2018, the terminal will become an international hub for seaborne trade and it will strengthen Indonesia’s logistics chain.
Surabaya is the capital of Eastern Java and the second largest city in Indonesia. The city lies on the northern shore of the island at the mouth of the Kalimas River and is an important port. Dredging company Van Oord is working on the construction of a business park, the Java Integrated Industrial Port Estate. The project involves dredging 4,000,000 m3 of sand from the sea bed and using it to construct five islands with a total area of 220 hectares. The contract will also include the installation of rock.
The second assignment is the expansion of the harbour for the Manyar Port Terminal. This project involves widening the existing channel to 150 metres and deepening it to -13 metres. A total of more than 10 million m3 silt will be removed and dumped at sea. Furthermore, one or two shipwrecks must be removed. The widening and deepening of the access channel will boost further economic development of the port.
